DVT Eclipse IDE Tooltips - How to Inspect Method/Macro Call Arguments and Port Connections

Overview

Have you ever had to change one argument in a function call which spans multiple lines? This video shows you how easy it is to inspect method argument mappings using DVT.

The same feature works for macro calls and module or entity instantiations with ordered port connections.

Details

When using the DVT autocomplete functionality to call a method, a pop-up lists all the method declaration arguments — their name, type, direction, and default value. This helps you keep track of the argument mapping.

Note that the argument under the cursor is always highlighted in bold font.

Getting Information for Existing Function Calls

To get the same information for an existing function call in your code, simply place the editor cursor on an argument and press Ctrl-Shift-Space.

This feature is also available for:

• Macro calls
• Ordered Port Connections
• Non-ANSI Style Module Declarations
